So I have an LED board that has multiple colors. Each color has a unique positive however all the negatives on the board are shared and there is no way to separate them. So my problem comes when plugging in multiple PWMs. I have one for white and one for blue. Because the PWM works on the negative and the negative is shared the two channels dim based on which PWM have the highest voltage (or something like that I'm guessing.....). I want them work individually Is there a way to rewire a PWM to switch on the + instead of the negative? Or some other way to achieve this from the PWM to the LED board? Or maybe reverse polarity of the DC current after it exist the PWM?
I know I could always just buy a new LED board and start over but I would rather not. Its all run by a 15v 2a DC power supply. Ideally it would be great if I could do something after the PWM between the LED and PWM. I have a plastic manual PWM and I also have a digital PWM that has microcontroller, digital display, timer, etc... So ideally I am hoping for a simple solution if possible. Or at least knowing its not reasonably possible someone with minor DC and LED knowledge.
